To all whom it may concern.

Be it known that I, EDWARD E. CLARK, a citizen of the United States, residing at Junction City, in the county of Geary and State of Kansas, have invented certain new anduseful Improvements in Antivibrating' Devices; and I dodeclare the following to be a full, clear, and: exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the" same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to an anti-vibrating device for' motor vehicle engines and the primary object is to provide a device for eliminating the excessive vibration of the motorduring operation.

In certain types of engines the vibratory action is so excessive as to become quite ob jectionable so I have provided an easily applied attachment which will relieve the vi-' bratory action, particularly the sidewise motion, and the invention consists in certain novel parts and combinations of parts, all of which will be specifically referred to hereinafter, reference being had to the accompanying drawings, in which- Fig. 1 is an end view of a conventional form of engine to which my invention is applied.

Fig. 2 is a perspective view of the-attachment removed.

Fig. 3 is a sectional view through one arm of the yoke and through one of the clamps, the clamping screw being shown in elevation.

' Fig. 4 is a detached perspective view of one of the chassis side bars in one end of one of the yoke arms, and

Fig. 5 is a fra mentary view of a slightly modified form 0 arch.

Referring now to the drawings by numerals of reference 1 designates an internal combustion engine which may conform to common gas engine practice and it is shown as mounted upon the side bars 2 and 3 of a chassis of a motor vehicle.

In order to reduce the vibratory action of theengine, I provide a yoke consisting of two vertical, curved members 4 and 5 having outstanding lower end members 6 and 7 which engage underthe top flanges of the channel-shaped members 2 and 3 and are secured thereto by fastening devices 8 and 9 indicated as'bolts.

The upper ends of the arms-4 and 5 are curved inwardly to provideoverlapping portions 10 and 11 which may be fastened together by bolts'12 and 13. Near the upper ends of the'arms 4 and 5 are headed screws 14 and 15 with clamping pads 16 and 17 loosely connected thereto so that they may clamp. against the sides of the head 18 of the engine 1, the screws being provided with jam nuts'19 and '20 to hold them against turning as will be well understood. The

yoke is made of two members so as to facilitate its application and removal and when the parts are in position as shown in Fig. 1 the vibration will be reduced to a minimum if not wholly eliminated.

In Fig. 5 I have shown the arch having the two side arms integral, that isthe arch will conform to the generic construction shown in Fig.1 except instead of having the arms overlapping, the arms will be joined as at 21 to make a continuous arch structure. In other respects the arch will conform to the preferred form. The modified form is shownmerely because it is more applicable 1E0 certain types of cars than the preferred 'orm.

VVhatI claim and desire to secure Letters Patent is y 1. In combination with the chassisof a motor vehicle and an enginecarried thereby, of a yoke having arms attached to the v chassis at opposite sides of the engine, and

an arched body part overlying the engine and means on said body art bearingagainst the engine at opposite sides thereof to brace the same.

2. In combination with the chassis of a motor vehicle and an engine carried thereby,

of a yoke having arms attached to the chassis and a central arch portion overlying .the engine and clampson the arch portion bracing the "engine at opposite sides thereof.

3. An anti-vibrating device for motor vehicle engines, comprising a yoke having an arched body portion and clamps on opposite sides of the body portion adjustable to engage opposite sides of the engine to which the device is ap lied.

' 4. An anti-vi -rating device for motor ve- Vehicle and means carried by the yoke for 10 bearing against 0 posite sides of the engine. In testimony w ereofI afiix my signature.
